Darren Sproles diagnosed with an ankle sprain, fantasy day could be done

New Orleans Saints running back Darren Sproles went to the locker room in the first quarter of Sunday's game against the Jets. Sproles will not return due to an ankle sprain., according to reports. The Saints announced he is undergoing testing for concussion symptoms and his return is questionable.

Sproles was hit hard by New York Jets safety Antonio Allen and went to to the ground awkwardly. After a brief moment on the sidelines, he was escorted to the locker room by the training staff.

So far, the Saints have been using Pierre Thomas more and have run some slip screens to get him the ball in the open field. Brees has also been looking at Lance Moore on intermediate routes.

Fantasy impact: The Saints have counted on Sproles as one of Drew Brees' favorite targets and the loss of him for an extended period of time would be devastating. This injury is bad news for Sproles owners. He's not too strong in the stature department, so the big hit he took may have keep him out of the lineup for next week and beyond. Pierre Thomas becomes an absolute must-start guy in PPR leagues while Lance Moore is also a nice pickup for now.
